Method for managing and allocating resources in a clustered computing environment

ABSTRACT

This present invention is directed towards a container orchestration method such as Kubernetes in which pods monitor themselves to determine if they are likely to require additional resources or vertical scaling within a given timeframe. If the pod determines that it will need additional processing power it notifies the state manager to begin allocating these resources on the same node or a different virtual or physical node before the CPU usage reaches 99%+. The state manager receives this request and allocates the necessary resources ahead of time. When the pod&#39;s CPU usage reaches 99%+, the state manager will remove the pod from the existing node and moves the application to the new pod on a different node in which sufficient resources are allocated. This invention brings about efficient utilization of nodes.

FIELD OF THE INVENTION

The present disclosure is directed generally to a method for managing available resources in an open source computer cluster environment.

BACKGROUND

Virtualized computing environments (VCEs) are known. VCEs can be stored as “images.” A new active instance of the VCE can be instantiated from the image. Two types of VCEs are virtual machines and containers. A container is a VCE that uses operating-system-level virtualization. This refers to an operating system feature in which the kernel allows the existence of multiple isolated user-space instances, called containers. These isolated user-space instances may look like real computers from the point of view of programs running in them (sometimes herein referred to as “containerized applications”). A computer program running on an ordinary operating system can see all resources (connected devices, files and folders, network shares, CPU power, quantifiable hardware capabilities) of that computer. However, programs running inside a container can only see the container's contents and devices assigned to the container.

“Clustered computing environments” (sometimes herein referred to as a “clustered environment”), as that term is used herein refers to a group of interconnected computers that are working together as one unit. Within a cluster, individual computers can be coupled either loosely or tightly. A loosely-coupled cluster consists of computers that are running with a minimum communication and cooperation among them. This results in efficient usage of each individual computer, but limits the amount of coordination and sharing of workloads. A tightly-coupled cluster consists of a group of computers that are cooperating to a great degree among each other, coordinating and sharing workload, and communicating status details on a continuous basis.

Clustered computing environments typically include “nodes.” The term “node” is herein used to mean a computing machine in the clustered computing environment.

As the term is used herein, “computing resources” is defined as measurable quantities in a computing environment that can be requested, allocated, and consumed. Computing resources may include, but are not necessarily limited to the following types of computing resources: CPU, memory (RAM), node disk space, networks, servers, processing, storage, applications, and virtual machines.

Kubernetes is developed for managing containerized applications in a clustered environment. Today we have very complex software applications. These need to be deployed and updated at a very rapid pace. With many containers, it becomes difficult to manage and keep each running in production. On the other hand, each of these containers will require replicas for scale out and high availability.

Management means the process of automated arrangement, coordination and management of complex computer systems, middleware and services. With it, you can schedule and deploy any number of container replicas onto a node cluster and Kubernetes will take care of making decisions like which containers go on which servers.

SUMMARY

The invention revolves around creating a separate node within the cluster, for example a Kubernetes cluster, called a “state manager”. This state manager uses a “race for resource principle” in order to manage the resources used by other nodes and pods inside the cluster. Its job is to facilitate automatic vertical scaling of applications deployed within a cluster.

DETAILED DESCRIPTION OF EMBODIMENTS

Some embodiments of the present invention may recognize one, or more, of the following problems, challenges and/or opportunities for improvement with respect to the current state of the are: (i) if a node is consistently running at 70% CPU usage and the node CPU usage starts to increase over time, it may be necessary to use resources from a different node to accommodate the increased usage; (ii) if all nodes are operating at or near capacity a new node with additional capacity may need to be created to accommodate the increased usage; (iii) such node creation takes time and will therefore result in some downtime with regard to the containerized applications that are in need of the additional capacity; (iv) there is a need in the art for a tool that can manage and allocate computing resources amongst containers in a clustered environment; (v) there is a further need in the art for a tool that can create new capacity before it is actually needed such that its capacity is ready to be allocated as soon as it is needed.

The present disclosure describes a computer based tool for using a state manager to perform a pod-based vertical scaling in a multi-tenant node based environment in a cluster environment, for example, a Kubernetes cluster. Some embodiments of the present invention may include one, or more, of the following features, characteristics, advantages and/or operations: (i) a tool that balances computing resources amongst containerized applications in a cluster environment; and/or (ii) when one container is in need of additional computing resources to run effectively, responsive allocation of computing resources amongst the containers in the clustered environment.

Referring to FIG. 1, in one embodiment, is a computer cluster environment, designated generally by reference numeral 10, essentially comprising at least one cluster manager computer 12 and a plurality of working computing machines, referred to as nodes, 14, with a plurality of containerized computer applications, referred to as pods, 16 stored on each node 14, and a state machine/manager 18. The cluster master 12 runs the cluster's control plane processes, including the API server, scheduler, and core resource controllers. The master's 12 lifecycle is managed by the cluster's engine when a cluster is created or deleted. This includes upgrades to the version running on the cluster master 12, which the engine will perform automatically, or manually if desired to upgrade earlier than the automatic schedule.

The master 12 is the unified endpoint for the cluster 10. All interactions with the cluster 10 are done via API calls (e.g., Kubernetes API call), and the master 12 runs the API Server process to handle those requests. API calls can be made directly via HTTP/gRPC, or indirectly, by running commands from the Kubernetes command-line client (kubectl) or interacting with the user interface in the GCP Console.

The cluster master's 12 API server process is the hub for all communication for the cluster 10. All internal cluster processes (such as the cluster nodes, system and components, application controllers) all act as clients of the API server; the API server is the single “source of truth” for the entire cluster.

The cluster master 12 is responsible for deciding what runs on all of the cluster's nodes 14. This can include scheduling workloads on pods 16, like containerized applications, and managing the workloads' lifecycle, scaling, and upgrades. The master 12 also manages network and storage resources for those workloads.

The master 12 and nodes 14 also communicate using the cluster's APIs. Each node 14 is a worker machine that runs containerized applications and other workloads in pods 16. The individual machines are Compute Engine VM instances that the cluster engine creates when the cluster 10 is created.

Each node 14 is managed from the master 12, which receives updates on each node's self-reported status. Some manual control over node lifecycle may be exercised, or the engine can perform automatic repairs and automatic upgrades on the cluster's nodes 14.

Each node 14 runs the services necessary to support the pods 16 thereon (e.g., Docker containers that make up the cluster's workloads in Kubernetes). In Kubernetes, as an example, these would include the Docker runtime and the Kubernetes node agent (kubelet) which communicates with the master 12 and is responsible for starting and running Docker containers scheduled on that node 16.

Each node 16 is of a standard Compute Engine machine type that can be selected when a cluster 10 is created. The machine type specifies a particular collection of virtualized hardware resources available to a virtual machine (VM) instance, including the system memory size, virtual CPU (vCPU) count, and maximum persistent disk capability. For the n1 series of machine types, for example, a vCPU is implemented as a single hardware hyper-thread on one of the available CPU Platforms. Each has, for example, a fixed collection of resources such as 3.75 GB of memory per vCPU, 16 persistent discs, and 64 TB maximum size for each persistent disc.

In cluster 10, there may also be a number of special containers that run as per-node agents to provide functionality such as log collection and intra-cluster network connectivity.

Some of a node's resources are required to run the engine and various node components necessary to make that node 14 function as part of the cluster 10. As such, there may be a disparity between a node's total resources (as specified in the machine type documentation) and the node's allocatable resources in the engine. To inspect the node allocatable resources available in a cluster 10, standard commands may be run, with the returned output containing capacity and allocatable fields with measurements for ephemeral storage, memory, and CPU, as an example.

Allocatable resources are calculated in the following way: Allocatable=Capacity−Reserved−Eviction Threshold. For memory resources, the engine reserves the following in a Kubernetes cluster:

25% of the first 4 GB of memory

20% of the next 4 GB of memory (up to 8 GB)

10% of the next 8 GB of memory (up to 16 GB)

6% of the next 112 GB of memory (up to 128 GB)

2% of any memory above 128 GB

The engine serves an additional 100 MiB memory on each node for kubelet eviction.

A request for resources for pods 16 or to limit their resource usage may be made.

It is possible to manage local ephemeral storage resources as is done with CPU and memory resources. System reservations for local storage are made primarily for disk space used by container images.

If a node 14 does not consume all reserved storage, Pods 16 are still able to use the space. This does not prevent disk space from being used in any scenario.

Allocatable local ephemeral storage resources are calculated using the following formula, with an eviction threshold of 10% of storage capacity: Allocatable=Capacity−Reserved−Eviction Threshold

The State Manager 18 is a program which could run on a server which is external to the cluster 10, and would be able to access the pods 16 within the system through a proxy or load balancer, which would be built into the cluster 10. It would be advantageous to have replicas of the state manager 18, in case the server on which it is running has any unexpected downtime.

The state manager 18 could also, however, be deployed within the cluster 10. This would bring the advantage of having lower latency on the communication between pods 16 and the state manager 18. In this case the state manager 18 would be replicated across multiple nodes 14 within the cluster 10 to ensure redundancy.

The individual pods 16 within a cluster 10 are, as described above, aware of their resource usage. A known command can be run within a pod 16 which will return various usage metrics of the host, for example the top command on a unix based system. There are also ways of monitoring resource usage which are built into Kubernetes, such as Prometheus (https://github.com/prometheus/prometheus), which enables the exporting of pod metrics to an endpoint.

There will be a program running on a loop within a processor of each pod 16 which will periodically initiate a POST HTTP request to the state manager, notifying it of the desired capacity in the case where the pod needs more resources. The desired capacity could be one of many pre-defined buckets of resources e.g. 2 GB, 4 GB, 8 GB of memory, and the pod 16 could simply request to enter the next bucket when its own resources are approaching the upper boundary of the previous bucket. The creator of the application could also inject custom logic and rules into the decision of when scaling needs to occur.

It is the job of the state manager 18 to handle the vertical scaling of the pod 16 once the pod 16 has requested additional resources. If there are enough resources available within the current node 14 (which the state manager 18 will store), then the pod 16 will be scaled within the current node 14. Otherwise, the state manager 18 will create a new node 14 within the cluster 10 and handle the transfer of the pod 16 to the new node 14, with the requested resources.

The present invention may be a system, a method, and/or a computer program product at any possible technical detail level of integration. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.

Currently container orchestration systems such as kubernetes scale out the pods onto “already existing nodes”. This introduces a limitation as if all nodes in the cluster are full and a pod needs scaling kubernetes does nothing. The state manager 18 solves this by automatically creating a new “node” with more resources when needed.

Creating a new node can be a timely process and as such the process of moving a pod to a newly created node to vertically scale it would be more efficient when pods are self-monitored. This would allow the pods to give some forewarning to the state manager so that it can decide if a new node needs to be created and if so start the process to create a new node before it is critically needed. For example:

A node is consistently running at ˜70% CPU usage

The node CPU usage starts to increase over time

A threshold could be configured at a predetermined threshold, 90% CPU usage for example, that when hit sends a message to the State Manager 18 to indicate that it will soon need a new pod 16 with greater CPU capabilities.

The state manager 18 can at this point determine whether it is likely that a new node 16 will need to be created to accommodate this request or if there is an already available node 16 with sufficient free space for a pod 16 with a need for increased resources.

Given that it is determined that a new node 14 is required it can start the process early hence cutting down the time where a pod 16 is in the process of being vertically scaled.

Once the pod 16 hits the point where it definitely needs to be vertically scaled (e.g. 99%+ CPU usage) the new node 14 will already be either in the process of being created or is already ready for use. This brings about efficient utilization of nodes 16.

Each pod in the cluster monitors itself (as opposed to an external monitoring system), and makes request for more resources to the state manager. The ability for the pod to monitor itself, will be essential for the process.

In an aspect, a resilient solution is provided as there is not a single point of failure in terms of monitoring the pods 16 in the cluster 10. If the State Manager 18 fails over the other pods 16 can still be aware of the fact that they may require vertical scaling and may be able to take some secondary action given that vertically scaling is not an option, such as error messages/distress signals.

The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.

Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network.

A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.

Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).
